been wondering and trying to figure out this problem for years!

i have a 1990 toyota pickup currently trailgear 5" sas and 63"chevy springs. i currently have the aggrivating issue of, instead of my rear end squating when i take off at a light or whenever, it actually lifts and always has. the truck did this with the toyota springs and ifs as well. i am about to be tearing the rear end down to rebuild a bunch of things and want to know what i need to do to cure this problem???

 

Ladder bars/ links would probaly help it stick a video camera under there and drive it around to see what's happening
personally I think when your taking off your axle is pulling the shackles foward/down which would lift the truck

 

One word. Antisquat

Big lift, big tires makes your antisquat go through the roof. Long torque arm will help. Or link it, could drop the front perch down but with 41s i think leafs your gonna have to live with some of it.

At least with my limitd knowledge.
Draw a lin from the tire contact patch through front spring eye to the front axle center line. As an example if the line crossed at your center of gravity( i usually just use top of the dampner)it would be 100%. No rise no drop

 

any axle wrap?
